JOHN e HEUMANN INVENTOR ATTORNEY Patented May 3, 1938 UNlTED STATESFATENT @FQE 3 Claims.

The protector of this invention is a shield guarding orices of the body,such as mouth and nose, and also serves to support filters, absorbents,medicaments', inhalants, disinfectants or germicides to be applied tosaid orifices.

It is one object of this invention to intercept direct or straightaccess to the said orifices.

I further arrange my protector so as not to impede breathing or speech.

Another obje-ct of my invention provides for properly positioning orsecuring the protector.

Still another object of my invention provides for means securingsuitable carriers for medicaments etc. o n the protector.

These and other objects of my invention will be more clearly recognizedfrom the following description in connection with the appended drawing,in which:

Fig. 1 shows a back view of a protector of my invention.

Fig. 2 shows a corresponding central crosssection.

Fig. 3 indicates the back view of a symmetrical half of a modificationof my protector.

Fig. 4 shows a corresponding central crosssection.

Fig. 5 is a back View of another modification of my invention.

Fig. 6 is a corresponding central cross-section.

Fig. 7 illustrates, in a detailed view,`an adjustable holding featureused for my protector.

Fig. 8 shows a cross-section of another arrangement of my protector.

Fig. 9 is the back view of another modification of my protector. V

Fig. 10 is a corresponding central cross-section.

Fig. 11 illustrates the use of a protector of my invention.

Similar numerals refer to similar parts throughout the various views.

The shield of my protectors is generally made of stiff, exible material,Celluloid for instance. In certain instances, for instance where it isfolded over and engagesupon fabrics slid thereunder, I rely on theresiliency of the material of the shield, for the purpose of clamping,stretching or detachably holding the fabric.

The shield S of Figs. l and 2 vis shaped and perforated so that it maybe positioned over the mouth and nose, in the position indicated in Fig.11 by means of a suitable string or elastic slung through suchperforation. Along the central, part the top and bottom edges I5 and Ilare folded back onto the shield. A piece I8 of gauze or absorbent ormedicated material may be (Cl. 12S-139) slipped underneath thefolded-over part I6 and Il and will be clampedly engaged thereby uponthe back of the shield S. The air inhaled or eX- haled by the user of myprotector vwill flow over and Contact the piece I3, which absorbs ormedi- Cates foreign matter. The piece I3 may contain medicaments ordisinfectants which slowly evaporate or volatilize and/ or absorbentliquid may be applied thereto.

In the modifications of Figs. 3 Aand 4 suitable hooks I9 take hold ofthe material of the shield S, and extend up and down from the edges ofthe folded-over parts i6 and Il in the back of the shield. The absorbentmaterial or gauze 2U is perforated, and through the perforations extendi the hooks E9 so that the material 2l) is stretched in theV back of theshield S, in "front of thenasal and/oral orifice. i

Instead of providing eyelets in the shield for the purpose of extendinga string or an elastic therethrough, around the head or over theauricle, ear 2l may be suitably attached to the shield, on oppositesides thereof, then fastening means areslung therethrough around thehead or over the ear, or a bow 22, is passed therefrom over the root ofthe auricle.

The bow 22 comprises a tube 23, which is exemplarily close, flattenedand transversely perforated at one end where it is linked to the ear 2I. Into the open end of the tube 23 slidably extends the straight end ofthe hook 24. The hook 24 may be provided with a flat, perforated end 25,a looped wire 26 suspendedly extending through said perforation.

The free ends of the wire 26 may be bent back upon themselves, and it ispreferably made of a at spring or resilient wire, so that it normallyassumes the shape indicated in Fig. 7.

The free ends of the wire ZE may be momentarily pressed together,inserted in the tube 23 ahead of hook 2li, and the released wire willfrictionally engage upon the inside of the tube, as indicated in Fig. 5,sol that the hook 24 is normally securely positioned in the tube 23, butmay be adjusted therein, in order to provide for the correct length ofthe bow, as required by the indiv'ldual user in securing the shield in aposition in which it is strapped without undue pressure over mouth andnose, resting upon the chin, the bow retracting the lateral ends of theshield.

The modified protector of Fig. 5 adds the horizontal platform 28 as anextension of folded back part I6 of the shield S. The free end 29 of theplatform is folded back over the platform, and provides a clamping orengaging means for absorbent material 30. Under these circumstances thematerial I8 protects the mouth only, the material 3U protecting thenose.

Hook 3| may be cut out of the shield S in the plane thereof, asindicated in Figs. 9 and 10. The gauze 32 is strapped over the hooks 3|in a manner analogous to the modification of Figs. 3 and 4. The corners33 of the gauze will then be disposed to the front of the shield. Thefolded back bottom edge i1 may be used in connection with thisarrangement, as in the prior modications, in order to prevent a cuttingof the chin.

Hooks 34, similar to the hook i9 of the modifications of Figs. 3 and 4,and to the hook 3l of Figs. 9 and 10, are applied to the modification ofFigs. 5 and 6, the absorbent material may be strapped over the saidhooks 34 and will then extend over the back of the platform 28, asindicated in Fig, 8, thus being closer to the nose and to the mouth. Thegauze or absorbent material I8 may be dispensed with under thesecircumstances, or it may be provided, and may for instance be medicated,the medicament contained therein reacting through the gauze 35. The backedge 36 of the platform 28 is shown to be folded down.

It should be noticed that the folded over edges like I6 and l1 reducethe transverse flexibility of the material of the shield, particularlywhen the absorbent material is wedged therebelow. I thereby gain theadvantage, that the shield, particularly adjacent to the mouth and thenose, does not lie flatly against the face, but provides for a certainamount of clearance, which offers ample space for circulation of the airto be breathed in and out.

When, however, more circulation of air is required, or the shield liestoo close to the skin, as might for instance be the case in thearrangement of Figs. 9 and 10, because there the upper edge is notreinforced, the shield may be suitably perforated as indicated at 37, inFig. 9.

Although I have shown and described one form of embodiment of myinvention in detail, yet I do not Wish to be limited thereby, except asthe state of the art and the appended claims may require, for it isobvious that various modications and changes may be made in the form ofembodiment of my invention, Without departing from the spirit and scopethereof.

What I claim is:

1. In a protector for mouth and nose, absorbent material, a flexibleshield with a bent-over edge formed in the material of said shield andsupporting said material, and elongatable bows extending from saidshield adapted to lit over the ears, so that said bows may be set to iexsaid shield over mouth and nose and then said edge Will clamp onto saidshield a piece of said absorbent material inserted thereunder.

2. In a protector for mouth and nose, absorbent material, a flexibleshield supporting said ma* terial, bows extending from said shieldadapted to t over the ears, telescoping members in said bows, and aspring attached to one such member and frictionally but slidablyengageable upon another one of said members.

3. In a protector for supporting absorbent ma terial in front of noseand mouth, an uninterrupted flexible shield adapted to rest upon the tipof the nose and upon the chin, a platform extending like the center legof a T from the back of said shield, so that it may extend underneaththe nose, and means for engaging and stretching said material from thetop to the bottom of said shield over said platform.
